To ctZZ whom it may concern.-

Be it known that we, ALBERT DE DION and GEORGES BOUTON, citizens ofFrance,and residents of Puteaux, in the Department of the Seine, France,have invented a new and usefullmprovement in Igniting Devices for Gas 1or Like Motors, (for which we have obtained Letters Patent in GreatBritain, dated October 21, 1895,No.19,735; in France, dated September13, 1895, No. 250,259; in Germany, dated October 28, 1895, No. 87,352,and in Switzerland, dated October 17, 1895, No. 11,033,)01": which thefollowing is a specification.

This invention consists in the arrangement of devices for ignitingexplosion engines which will allow of the following advantages: First, acontactmaker or circuit-closer similar to those used with an ordinaryinductioncoil can be placed at any desired distance from the coil, andits movements to establish and disestablish the circuit of the primaryof the induction-coil may be effected by mechanical means at the exactmoment when a spark is required for igniting the explosive mixture of agas1notor; second, the proper movements of the circuit-closer may be soproduced that they will complete the circuit while the motor is turningat its normal speed or at a lower speed, but will be inoperative if themotor is turning too quickly, thus taking the place of aspeed-regulator. To obtain these results We employ apparatus such as isshown diagrammatically in the accompanying drawing, in which the figureshows the essential parts of a gas-engine and illustrates our inventioncombined therewith.

Referring to the drawing, the reference-lettor A indicates thecrank-chamber, and B the cylinder, of any ordinary gas-engine. At anysuitable point relatively to said engine we place an induction-coil O,the primary coil of which is supplied with current from a battery orother source of electric energy D. At whatever point the coil Ois placedwires to and Z) are led from the terminals of the primary coil tobinding-posts c and cl, in one of which a contact-point e is mounted,while from the other a vibratory strip or circuit-closer E is mounted insuch manner that it lies very near 7 the extremity of the contact-point0, beyond which said strip extends for some little distance, a shoe Fbeing mounted upon its free or unsupported end. In suitable relation tosaid shoe F is a disk G, mounted upon a shaft H and provided at onepoint in its periphery with a notch f.

The shaft H is revolved by any preferred means. 7

The arrangement of the parts is such that as long as the shoe F restsupon the periphcry of the disk G the conducting-strip E will be held outof electrical contact with the extremity of the contact-point 6. shoe Ffalls into the notch f, however, the elasticity of the circuit-closer Ecauses it to come into contact with the point e, and the circuit of theprimary of the induction-coil O is thereby completed for a moment oruntil the continuous revolution of the disk G causes said shoe to belifted out of the notch. Thus a current of high tension is induced inthe secondary of the induction-coil O. The terminals of said secondarycoil are connected to two binding-posts K and L, and from saidbinding-posts wires M and N are led to and into the combustion-chamberor explosionchamberB, within which the extremities of said wires arebrought close together, the interval of separation between their endsbeing such that the high-tension current will readily jump across. Inpassing this interval of separation a spark is produced, having ampleigniting power to produce an explosion of the gas or gaseous mixture.

The flexibility of the circuit-closer E and the outline of the notch fmay be so regulated that if the motor turns too quickly a suflicientmovement of the circuit-closer to bring it in contact with the point 6cannot be obtained, since the shoulder f of the notch f will come intocontact with and arrest the circuitcloser before a full movement cantake place, thus preventing contact with the point 6. With thisarrangement the current is only used during the time of explosion.

Having thus described our invention, what we claim is- 1. A gas-ignitingapparatus for a gas-engine, consisting of a vibratory conducting-stripor WVhen the circuit-closer having a shoe, a conducting contact-point,Wires connected to both and to the terminals of the primary of aninduction-coil, and a notched disk upon the periphery of which the shoeof the circuit-closer rests out of contact with the point, and at eachrevolution falls into the notch an d closes the circuit of the primaryof the inductioncoil, substantially as described.

2. In explosionnnotors a device for igniting the explosive mixture byelectricity consisting" of a notched disk revolved by any suit ablemeans, a circuit-closer having a shoe resting on the disk and falling ateach revolution into the notch, a contact-point close to but out ofcontact with the circuit-closer save when the shoe thereon passes intothe notch in the disk and an induction-coil having the terminal of itsprimary connected to the circuit-closer and contact-point and theterminals of its secondary slightly separated in an explosion chamber,substantially as de scribed.

In testimony whereof We have signed this specification in the presenceof two snbscrih" ing Witnesses.
